Abstract: TRANSISTORIZED SINGLE ENDED PUSH-PULL AMPLIFIER        HAVING NO CROSS-OVER DISTORTION            ABSTRACT OF THE DISCLOSURE          An amplifier circuit comprising a single ended push-pull amplifying stage comprised of field effect transistors. A pre-amplifier stage formed of a differential amplifier is coupled to the single ended push-pull amplifying stage for supplying a signal thereto.  The output terminals of the differential amplifier are connected to the respective gate electrodes of the field effect transistors included in the single ended push-pull amplifying stage, and load impedance means couple the differential amplifier output terminals to the source or drain electrodes of the field effect transistors. A variable current source is connected to the differential amplifier for controlling the current flowing through the differential amplifier as a function of variations in the operating voltage that is supplied to the load connected to the single ended push-pull amplifying stage.  Variations in this operating voltage cause corresponding changes in the differential amplifier current to thereby change the bias level of the signal supplied by the differential amplifier to the single ended push-pull amplifying stage so as to maintain the idling currents of the field effect transistors at a sub-stantially constant level, thus preventing the occurrence of cross-over distortion.        -i-

Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a wall drainage system for foundation walls which has particular though not exclusive application to the provision of drainage between shoring walls and concrete walls placed against such shoring walls.  The drainage system comprises a cover of water-pervious filter material placed over the shoring wall to prevent passage of soil particles and a water-impervious cladding located over the cover.  The cladding is formed of generally rectangular panels of water-impervious material arranged in edge-to-edge abutted relationship.  One face of each panel is located against the cover, and has a plurality of vertical drainage grooves which are in fluid commun-ication with those of any subjacent or suprojacent abutting panel.  Each panel of a lowermost row of panels has a plurality of horizontal drainage grooves formed in the other of its faces, which are in fluid communication with the vertical drainage grooves of the panel and which are also in fluid communication with the horizontal. drainage grooves of any abutting panel in the lowermost row so that these lowermost panels define a horizontal drainage conduit.  A water-pervious filter material pre-vents entry of soil particles into the horizontal drainage conduit.  A telescoping sleeve is placed in communication with the horizontal grooves of one or more of the panels of the lowermost row to drain the collected water into the drainage system of the building being constructed.

Abstract: Abstract A high frequency RF gasket is disclosed which provides an electromagnetic seal between a first and second piece of a shielding enclosure.  The gasket comprises highly resilient finger projections which are attached to and project out along the perimeter of the first enclosure piece.  The relative mating arrangement of the gasket, and first and second enclosure piece is such that a small force imposed on said first enclosure piece is resisted by a much larger resistance force along the longitudinal dimension of the highly resilient finger projections as the fingers engage the second enclosure piece.  The larger resistance force causes sufficiently high pressure at the point of contact between the finger projections and the second enclosure piece so that the surface of the second enclosure piece yields to the finger projections.  Thus reliable electrical contact between the first and second enclosure pieces is obtained by piercing the surface of the second enclosure piece with the finger projection's point of contact with the second enclosure piece.

Abstract: ABSTRACT OF THE DISCLOSURE    A method of determining dTk isoenzyme levels of a human or animal body fluid or cell sample is disclosed herein.  The method includes the steps of reacting the sample with a substrate for the isoenzyme in the presence of a phosphate donor and a buffer system.  The amount of phosphorylated product formed is measured, that amount being proportional to the isoenzyme level.  The method uses (a) a buffer system at a pH ranging from 5 to 9 and which is present in a concentration of no more than 250 mM, (b) a substrate consisting of 2'-deoxy-5-halouridin, part of which has a radio-labelled 5-halogen, and which is present in a concen-tration ranging from 2 x 10-9 to 5 x 10-6M, and (c) the phosphate donor which is present in a concentration not exceeding 20 mM.  The sensitivity of the method permits measurement of minute amounts of dTk.  The method can be used for, e.g., the diagnosis, prognostics and monitoring of diseases involving altered ATP mediated dTk activity, e.g., cancers, tumours, and certain virus infections or altered CTP mediated dTk activity, e.g., HSV type 1, type 2, and VZV infections.

Abstract: ABSTRACT     Disclosed is a low noise microwave frequency synthesizer having a plurality of rapidly switchable output frequencies.  Two banks of oscillators (10)(20) are selectively mixed to yield a range of output signals of low phase noise and low spurious noise.  The first bank of oscillators (10) comprises low noise, highly stable oscillators of a frequency range below the desired synthesized output signal.  The second bank of oscillators (20) comprises low noise, highly stable oscillators of a frequency range lower than the first bank.  The signal from the second bank of oscillators is frequency multiplied (30) to a desired frequency range by a low multiplication factor and then mixed (41) with the signal from the first bank of oscillators.  Multiplied phase noise is reduced by using a low multiplication factor.  The upper sideband of the mixed signals is output as the synthesized output signal (50).  Rapid switching (11)(21) between oscillators in both banks provides a frequency range of synthesized output signals which may be rapidly stepped through as desired.

Abstract: ABSTRACT OF THE DISCLOSURE     A simplified fan and brushless DC motor employs an annular permanent magnet magnetized in segments about its circumference.  Each segment is oppositely radially mag-netized with respect to the preceding segment as one pro-cedes around the magnet.  Fan blades are located within the annular magnet.  A coil and electromagnet structure defining two pole pieces reside outside the permanent magnet annulus.          A Hall effect device switches the coil off and on in response to passage of the segments of the rotor magnet.  Thus com-mutated, the single coil affects rotation of the rotor and the fan blades.  A permanent magnet supported on the stator structure serves to magnetically detent the permanent magnet of the rotor, bringing the rotor to rest correctly for restarting.
